Welbeck at the double for first time in league for Arsenal

The Chilean, who was strongly linked with a move to rivals Manchester City during the summer, came off the bench in the 75th minute and, although he received a standing ovation from the majority of the 60,000 fans inside the Emirates Stadium, there were what appeared to be a few jeers audible.

They were second best throughout the game at the Emirates and Howe admitted they must show character ahead of a Friday Night Football clash with Brighton, live on Sky Sports Premier League.

"I don't know why [he was booed]", he added.

"Before every game I have a selection problem and I'm always going to have to leave top-class players out - especially offensively because we have many top strikers", Wenger told reporters.

Welbeck struck on six minutes on Saturday and wrapped up the points with a smart finish either side of Lacazette well-taken strike.

"Let's not forget that he was out for a long time", Wenger said of Welbeck.

"The interpretation of the attitudes is always very risky". Welbeck had numerous chances to complete his hat-trick, Ozil fired narrowly wide and substitute Francis Coquelin had a goal-bound effort blocked on his 100th Arsenal appearance.

Bournemouth have lost all four of their Premier League matches so far this season, having scored one goal and conceded eight. "We played well all over the pitch".

"I don't think losing the early goal helped, it was a poor goal to concede. On the ball we were negative, wasteful and slow and that is not like us".

Only a stoppage-time victor from Raheem Sterling prevented Bournemouth from taking a share of the spoils from Pep Guardiola's men but the loss here was a different matter.

"We hit the post and at 2-1 it would have been very much game on, but not only did we not score with that moment we conceded moments later which effectively ended the game".

"It is very, very disappointing from our perspective", added Howe. However, if Welbeck continues to perform and produce the way he did against Bournemouth, he'll continue to give his manager pause for thought, whether that's in terms of changes of personnel or a change of system.
